使用Javascript读取会话ID
问题描述：
是否可以使用javascript读取浏览器会话ID？
Is it by any means possible to read the browser session id using javascript?
答
是的。会话ID通过URL（ document.location.href ）或通过cookie（ document.cookie ）传输>），您可以检查是否存在会话ID。
Yes. As the session ID is either transported over the URL (document.location.href) or via a cookie (document.cookie), you could check both for the presence of a session ID.
